Mesocosm Study of Chemical Treatments on Methane Emissions in Oil Sands Tailings PondsPart I: Focusing on the Change of Microbial Communities and Tailings Dewaterability.

ABSTRACT: In this study, we proposed mitigation strategies to reduce methane emissions from oil sands tailings ponds and determined the extent to which certain chemicals (Na₂MoO₄·2H₂O, Fe₂(SO₄)₃, Na₂SO₄, and Na₃C₆H₅O₇·2H₂O) could affect the methanogenesis process. Lab-scale mesocosms were used to compare the amount of fugitive emissions between paraffinic and naphthenic producer tailings. The inter-relationships among different parameters, such as methane, water chemistry, residual bitumen content in tailings, and microbial community, were investigated before and after the methane inhibition process. It was found that under different chemical treatment regime
